The above graph covers the period of December 1990 to March 2008.
According to the latest numbers from Pingdom.Com, "There are more than 162 million websites on the internet today. We have come a long way baby since that first World Wide Web site. Back in January of 1996 there were 100,000 websites, and if you go back to mid-1993 there were only a total of 130 sites! Not much need for Google in those days,"
